Product details
Overview
SS16ALH from Taiwan Semiconductor is a 1A, 60V Schottky barrier surface-mount rectifier in Thin SMA package, featuring low forward voltage (0.58V typ at 1A/25°C), high surge capability (30A IFSM), AEC-Q101 qualification, and junction temperature up to 150°C - used in automotive-grade DC/DC converters and compact AC/DC adapters.
For engineers reviewing the SS16ALH datasheet, SS16ALH pinout, SS16ALH application, or SS16ALH equivalent, key selection criteria include reverse voltage rating (60V VRRM), thermal resistance (24°C/W RθJL), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance for high-reliability power conversion designs.
Technical Context
The SS16ALH operates as a single-die Schottky rectifier optimized for high-frequency switching applications. Its 60V repetitive peak reverse voltage and 1A average forward current support efficient energy transfer in space-constrained topologies where low conduction loss is critical.
Thermal performance is defined by RθJL = 24°C/W and RθJA = 78°C/W on a 5mm × 5mm Cu pad PCB. The device exhibits TJ-dependent forward voltage drop (0.52V max at 1A/125°C) and low leakage (≤100µA at 25°C, ≤40mA at 125°C), enabling stable operation across automotive temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum reverse blocking voltage before breakdown; defines safe operating range in 48V system rails and buck-derived outputs. |
| IF(AVG) | 1 A - Continuous forward current rating; supports compact 5–12W SMPS output stages without forced cooling. |
| VF @ 1A, 25°C | 0.58 V (max) - Low conduction loss reduces power dissipation and improves efficiency in high-duty-cycle converters. |
| IFSM (8.3ms) | 30 A - Peak surge handling capability enables robustness against input transients and inrush events. |
| TJ(max) | +150 °C - Extended junction temperature rating allows deployment in under-hood automotive environments. |
| RθJL | 24 °C/W - Low junction-to-lead thermal resistance facilitates heat transfer to PCB copper, reducing thermal derating needs. |
| CJ @ 4V | 55 pF - Low junction capacitance minimizes switching losses and EMI in >100kHz DC/DC controllers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay SS16HE3_A/H | Same 60V VRRM, 1A IF, SMA package; VF = 0.55V max at 1A/25°C; no AEC-Q101 qualification. | Not validated for automotive use; suitable for industrial/commercial power supplies only. | Select when AEC-Q101 is not required and lower VF tolerance is acceptable. |
| ON Semiconductor SB160-T | 60V VRRM, 1A IF, DO-214AA (SMA) package; VF = 0.75V max at 1A/25°C; higher conduction loss. | Higher VF increases thermal load in high-duty-cycle applications; less suitable for thermally constrained layouts. | Select when legacy footprint compatibility with DO-214AA is mandatory and efficiency is secondary. |
Compared with SS16HE3_A/H and SB160-T, the SS16ALH delivers superior thermal performance (RθJL = 24°C/W), automotive qualification, and lower forward voltage - making it optimal for space- and reliability-critical 1A rectification where efficiency and qualification matter.

FAQ
What is the maximum junction temperature rating for SS16ALH?
The SS16ALH has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings in the official datasheet. This allows reliable operation in under-hood automotive environments and high-ambient industrial settings. Derating curves confirm usable current capacity down to 0.5A at 125°C ambient on standard PCB layouts. The SS16ALH's thermal resistance values (RθJL = 24°C/W, RθJA = 78°C/W) support this rating when mounted on a 5mm × 5mm copper pad.
Is SS16ALH AEC-Q101 qualified?
Yes, the SS16ALH is explicitly AEC-Q101 qualified as stated in the "FEATURES" section of the official Taiwan Semiconductor datasheet (Version B2103). This qualification covers stress tests including high-temperature gate bias (HTGB), temperature cycling (TC), and high-temperature reverse bias (HTRB), confirming suitability for automotive electronics applications such as body control modules and ADAS subsystems.
What is the forward voltage of SS16ALH at 1A and 125°C?
The SS16ALH forward voltage is specified as 0.52V (maximum) at 1A forward current and 125°C junction temperature, per the Electrical Specifications table. At 25°C, VF is 0.58V max under the same conditions. This temperature-dependent drop reflects Schottky behavior and is critical for thermal modeling in high-load DC/DC converters where the SS16ALH serves as the output rectifier.
Does SS16ALH have a halogen-free and RoHS-compliant construction?
Yes, the SS16ALH meets both RoHS Directive 2011/65/EU and IEC 61249-2-21 halogen-free requirements, as confirmed in the "FEATURES" section of the Taiwan Semiconductor datasheet. The molding compound is UL 94V-0 rated, terminals are matte tin plated, and the full material composition complies with environmental regulations for global electronics manufacturing and export.
What is the moisture sensitivity level (MSL) of SS16ALH?
The SS16ALH is rated at Moisture Sensitivity Level 1 per J-STD-020, meaning it has unlimited floor life and does not require dry pack or baking prior to reflow soldering. This simplifies SMT line integration and eliminates yield risk from popcorning during assembly - a key advantage for high-volume production of adapters and automotive modules using the SS16ALH.
